I see.  Both `C-x * c, C-x * i' and  `C-x * i, C-x * c, C-x * o'
seem to leave Emacs in the same state, neither of which is looking at
the tutorial.  The paragraph you mentioned talks about reading the
tutorial online, so it should probably be changed to `C-x * t', which
will set up the desired Emacs setup by itself, and a discussion of how
to switch between the info and Calc buffers.  In the future, perhaps
Calc commands that will manipulate the info buffer from within the Calc
buffer might be useful (for example, `i SPC' in the Calc buffer will
scroll the info buffer).

That's a good idea; I'll add a line like that to the info output.
